Countercurrent Contacting Device With Interleaved Deflector Blades

The patent merges multiple individual crossing elements into a single integrated grid structure formed from a continuous sheet of material. The grid pattern is created by cutting and folding the sheet, which combines what would otherwise be separate welded components into one monolithic structure, eliminating the need for welding while maintaining structural integrity

The continuous sheet is segmented into a grid pattern through cutting and folding operations that create the crossing element structure. This segmentation is achieved during the forming process rather than through assembly of pre-cut pieces, allowing the structure to be divided into functional crossing elements without requiring joining operations

The grid pattern is preliminarily formed by cutting and folding the continuous sheet before the final assembly step. The crossing elements are pre-positioned and pre-shaped through these forming operations, so that when the structure is completed, the elements are already in their correct positions and orientations without requiring welding or additional joining operations

The patent replaces the welding mechanical system with a forming system based on cutting and folding operations. Instead of using thermal or mechanical joining processes to assemble crossing elements, the structure is formed directly from a continuous sheet through geometric transformations, eliminating the need for welding equipment and processes
